Ingredients

Peanut Butter Base

  • 1 ½ cups creamy no-stir peanut butter
  • ¾ cup protein powder (vanilla or chocolate)
  • ¼ cup honey or maple syrup
  • 1 cup rolled oats

Topping

  • ¼ cup dark chocolate chips
  • Optional: Sea salt for topping

Instructions

  1. Make the Peanut Butter Base: In a large bowl, mix together the peanut butter, protein powder, honey or maple syrup, and rolled oats. Stir until all the ingredients are well combined into a thick mixture that holds together easily.
  2. Press into the Pan: Line an 8×8-inch baking dish with parchment paper. Transfer the peanut butter mixture into the dish and press it firmly and evenly into the bottom, forming a consistent layer.
  3. Melt the Chocolate: Place the dark chocolate chips in a microwave-safe bowl and melt them in 30-second increments, stirring thoroughly after each session until the chocolate is smooth. Pour the melted chocolate evenly over the peanut butter layer and spread it out with a spatula. Sprinkle a pinch of sea salt on top if using.
  4. Chill: Refrigerate the assembled dish for at least 1 hour to let the chocolate set and the bars to firm up nicely.
  5. Slice & Serve: Once the chocolate has completely hardened, slice the mixture into 12 to 16 bars. Store the bars in an airtight container in the refrigerator for up to one week, or freeze them for longer storage.

Notes

  • Use no-stir peanut butter to make mixing easier and achieve the best texture.
  • Protein powder flavor can be vanilla or chocolate based on preference.
  • Honey or maple syrup can be substituted depending on dietary needs or taste preferences.
  • For a vegan version, use maple syrup and a plant-based protein powder.
  • Add a pinch of flaky sea salt on top to enhance the chocolate and peanut flavors.
  • Keep bars refrigerated or frozen to maintain firmness and freshness.
  • Rolling oats can be swapped for gluten-free oats if needed.
